1 answer:

3 0

Amino acids are the building blocks of proteins. There are 20 different amino acids and all share five basic parts namely-

1. a central carbon atom

2. a hydrogen atom

3. an amino group

4. a carboxyl group

5. an R - group or side chain.

The R - group or side chain is what makes each amino acid unique.

There are two categories of amino acids:

1. essential amino acids - these are necessary for growth and maintenance of the body but cannot be produced by the body itself.

2.non essential amino acids - these can be synthesized by the body itself.

kvasek [131]

Answer:

The speed at which the reactants change to products over a given time.

Explanation:

A chemical's reaction rate is the change in the concentration of a reactant or a product with time (in moles per second).

Remember that during a chemical reaction, reactants are converted to products. Or what is the same, products are formed at the expense of reactants. This can be represented:

reactants → products

Therefore, the progress of a reaction can be followed measuring the decrease in concentration of the reactants or the increase in concentration of the products.

According to the temperature and other parameters, the reaction rate can increase or decrease.
