What is the protein PPT?
PROTEINS • The Molecules which yields amino acids upon hydrolysis are called proteins. • Proteins are natural polymer of amino acids. • The number of amino acids in a protein molecule may range from two to several thousands. • Protein molecules contain Nitrogen, Carbon, Hydrogen and Oxygen. Prepared by: Sidra Javed.
What is protein diet PPT?
Functions of Proteins Proteins are important for body building, growth, repair and maintenance of body tissues. Proteins are required for the synthesis of plasma proteins, haemoglobin, enzymes and hormones.
What are peptides PPT?
-Peptides (from the Greek word means “digested”) are short polymers of amino acid (monomers) linked by peptide bonds, the covalent chemical bonds formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule.
What are the 4 types of functional proteins?
Proteins are organized at four levels: primary, secondary, tertiary, and (optional) quaternary.
What are enzymes PPT?
Enzyme An enzyme is a protein or RNA produced by living cells, which is highly specific and highly catalytic to its substrates. Enzymes are a very important type of macromolecular biological catalysts.
What is nucleic acid PPT?
HETEROCYCLIC BASES Present in nucleic acids are divided into two types- PURINES and PYRIMIDINES. The two Purines present both DNA and RNA are adenine and guanine. The Pyrimidines cytosine is present in both DNA and RNA, whereas thymine is found in DNA only and Uracil is present in RNA only.
What is the PPT diet?
PPT diet describes a personalised postprandial-targeting diet. PPT diet can’t be generalised as it doesn’t include a set of guidelines to follow, unlike other diets. This diet’s effectiveness relies on its personalisation to the individual.
What are the sources of protein PPT?
ATTRIBUTES OF PROTEIN 8 Complete protein that has all amino acids including essential ones are meat, poultry, fish, dairy products, eggs, and soy. Incomplete protein sources include nuts, grains, fruits, and vegetables.
What is Ramachandran plot PPT?
The Ramachandran Plot • The two torsion angles of the polypeptide chain, describe the rotations of the polypeptide backbone around the bonds between N-Cα (called Phi, φ) and Cα-C (called Psi, ψ) • It provides an easy way to view the distribution of torsion angles of a protein structure.
What are the types of peptides?
Peptides are mainly categorized in three different ways: According to how many amino acids make up the chain: Oligopeptides have few amino acids, while polypeptides are longer chains—typically between 20 to 50 amino acids. Dipeptides, tripeptides, and tetrapeptides have two, three, and four amino acids respectively.
What are the 7 types of proteins?
Types of Proteins. There is a total of seven different protein types under which all proteins fall. These include antibodies, contractile proteins, enzymes, hormonal proteins, structural proteins, storage proteins, and transport proteins.
What are the 8 types of proteins?
What are the 8 types of protein?
- 1) Hormonal Protein. Hormones are protein-based chemicals secreted by the cells of the endocrine glands.
- 2) Enzymatic Protein.
- 3) Structural Protein.
- 4) Defensive Protein.
- 5) Storage Protein.
- 6) Transport Protein.
- 7) Receptor Protein.
- 8) Contractile Protein.
What are the factors affecting enzyme activity PPT?
Effect of enzyme, substrate, product concentration, time, temperature, pH and presence of activators and inhibitors. Effect of enzyme, substrate, product concentration, time, temperature, pH and presence of activators and inhibitors.
What are 5 properties of enzymes?
[1] enzymes act like biological catalysts that speed up reaction rates. [2] enzymes convert one form of energy into a more useful form of energy. [3] enzymes need helper molecules called cofactors. [4] enzymes are highly specific.
What is RNA PPT?
RNA (Ribonucleic acid ) RNA is a polymer of ribonucleotides linked together by 3′-5′ phosphodiester linkage Biochemistry For Medics 2.
What are the 4 functions of nucleotides?
Biological importance of Nucleotides
- Forms the constituents of DNA and RNA – They serve as building blocks of nucleic acids and are the carriers of activated metabolites for the process of biosynthesis.
- Involved in storing chemical energy.
- Required for DNA replication and RNA transcription in stages that rapidly divide.
What is malnutrition PPT?
Malnutrition is the condition that develops when the body does not get the right amount of vitamins, minerals, and other nutrients it needs to maintain healthy tissues and organ function.
Why is nutrition important PPT?
1 People need certain nutrients on a regular basis to maintain health and prevent disease. 5. Nutrients: Vitamins and Minerals Without the right amounts of vitamins and minerals, people may become deficient and develop deficiency-related diseases. Vitamins are chemical compounds found in food.
What are the 6 functions of proteins?
Proteins have multiple functions, including: acting as enzymes and hormones, maintaining proper fluid and acid-base balance, providing nutrient transport, making antibodies, enabling wound healing and tissue regeneration, and providing energy when carbohydrate and fat intake is inadequate.
What does Ramachandran plot tell you?
The Ramachandran plot shows the statistical distribution of the combinations of the backbone dihedral angles ϕ and ψ. In theory, the allowed regions of the Ramachandran plot show which values of the Phi/Psi angles are possible for an amino acid, X, in a ala-X-ala tripeptide (Ramachandran et al., 1963).
Why do we use Ramachandran plot?
Many of the angle combinations, and therefore the conformations of residues, are not possible because of steric hindrance. By making a Ramachandran plot, protein structural scientists can determine which torsional angles are permitted and can obtain insight into the structure of peptides.
What are the four peptides?
Naming Peptides
Dipeptide: consists of two amino acids. Tripeptide: has three amino acids. Tetrapeptide: has four amino acids. Pentapeptide: has five amino acids.
What is a peptide vs protein?
Peptides are generally considered to be short chains of two or more amino acids. Meanwhile, proteins are long molecules made up of multiple peptide subunits, and are also known as polypeptides. Proteins can be digested by enzymes (other proteins) into short peptide fragments.
What are the 3 parts of protein?
Amino acids are the monomers that make up proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom bonded to an amino group (–NH2), a carboxyl group (–COOH), and a hydrogen atom.
What are 5 types of proteins?
There are seven types of proteins: antibodies, contractile proteins, enzymes, hormonal proteins, structural proteins, storage proteins, and transport proteins.
