# Remark on Protein Collapse from a Random Walk

## TL;DR

This paper uses a mean-field approximation to analyze how heteropolymers rapidly collapse from a random walk conformation to a molten globule state driven by hydrophobic interactions, followed by a slower annealing phase.

## Contribution

It introduces a mean-field approach to model the collapse dynamics of heteropolymers, highlighting the two-stage process of rapid collapse and slow annealing.

## Key findings

- Rapid collapse from random walk to molten globule
- Hydrophobic interactions drive the initial collapse
- Slower annealing with minimal size change

## Abstract

I use a mean-field approximation to show the rapid collapse of heteropolymers from random walk size to a much smaller, molten globule state due to hydrophobic interactions, to be followed by a slower annealing process in which there is little change in overall size.
