Answer:

Potential targets:

1- DNA methyltransferases

2- Chromatin modifiers such as histone acetyltransferases, histone deacetylases, histone methyltransferases, etc.

3- Components of the RNA interference (RNAi) machinery such as Dicer, Argonaute, etc.

Explanation:

Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.

Answer:

Stored as fat

Explanation:

The body requires a variety of macro nutrients for building blocks to fortify the body and keep it functioning. One of the important building blocks are amino acids that are derived from proteins. These are broken down in the stomach by protein digestion enzymes by amylase, proteases and hydrochloric acid.

In the even that the body has taken in too many units of protein this will be stored in the liver as glycogen. This is a form of "animal carbohydrate" or "animal sugar."

The glycogen stores will remain there for a reservoir for energy whenever the body requires it. In the event of overeating the body will store the glycogen in a more concentrated form, fat via the fatty acid synthesis pathway.
